GARf-BRAKE.

SPECPIC'ATION forming part of Letters Patent No. 383,904, dated June 5,1888.

Application filed February 20, i888. Serial No. 264,560. (No model.)

To all whom t may concern:

Be it known that I, GEORGE B. QUIGG, residing at Thornton, in the countyof Cook and State of Illinois, and a citizen of the United States, haveinvented a new and useful Improvement in Car-Brakes, of which thefollowing is a specification, reference being had to the accompanyingdrawings, in which- Figure 1 is an under side view of a freightcarcontaining my improvements, the trucks being shown only at one end. Fig.2 is a central vertical longitudinal section of the same, the parts foroperating the brakes being out of action. Fig. 3 is also a centralvertical longitudinal section, the draw-bar being removed and thedevices which operate the brakes be ing shown in position for action.Fig. 4 is a detail, being a perspective of the yoke and rollers. Fig. 5is a detail showing the divided clutch. Fig. 6 is a detail, beingacentral crosssection through the clutch. Fig. 7 is a detail showing thecase and spring at the inner end Figs. 4, 5, 6, and 7 are enlarged.

My improvementis primarily designed to be used upon freight-cars.

The leading object of my invention is to provide a safety-brake whichwill be brought into action automatically whenever adjoining cars cometogetherin consequence ofthe slackening of the speed of the locomotiveorfrom other cause, and which will also be automatically released when thecars are again separated from each other, and to provide devices whichwill prevent the action of the brakes when backing, which I accomplishas illustrated in the drawings and hereinafter fully described. Thatwhich I claim as new will be set forth in the claims.

In the drawings, A represents the wheels of a freightcar truck, which islocated under one end of the car, as usual.

B B are two axles.

C is a drawbar provided with a spring, as usual.

Dis a yoke hinged at a to the under side of the car. As shown, this yokeis made of two bars, Z) c, placed at a little distance from each otherand having upon their ends bearings which support the rollers d d.

c e are two short connecting bars or rods permanently secured to theparts b c.

E is a rod supported in bearings secured to the car, so that the rod canhave a limited longitudinal movement. One end, r, of the rod projectsbeyond the car, and this end is arranged to come in contact with the'inside of the head of the draw-bar C. The other end is provided with acasing,f, on which is a hook or projection, f', arranged to engage withthe bar c. j

g is a coiled spring in the casef. @ne end of the spring is against acollar and the other end comes in contact with the head on the inner endof the casef.

his a coiled spring arranged to actupon the rod E.

F is a second rod supportedA so as to have a limited longitudinalmovement, the same as the rod E. This rod F extends to the opposite endof the car and projects a little distance therefrom, and this outer endis ar ranged to come in contact with the inside of the head of thedraw-bar. This rod or bar F is also provided with a case,f, which has ahook, f3, similar tof, to engage with the bar e. In this casef is aspring, g', similar to the spring g.

G G are brakes, and II H brake-bars arranged in the usual manner. 4

fi t' are collars Iixed upon the axle B. Between these collars there isa sleeve made in two parts, jlc, which parts are held loosely in placeupon the axle by means of ringsZZ, arranged in grooves in projectionsupon the two parts ofthe sleeve.

m is a rope, one end of which is attached to the roller d, from which itpasses under a roller, a, thence around the divided sleevej 7c, thenceover a pulley upon the outer brakebar, H, thence to the inner brake-ban,I-I, and thence to the roller d, to which it is secured.

o is a short piece of rope, one end of which is connected to the rollerd and the other end is connected to the rod E.

p is another short rope, one end of which is connected to the roller dand the other to the `rod or bar F.

As shown. the rod E is partly supported by a swinging link, q, and therod F by a link,q',

IOO

which aid inkeeping the inner end of the rods E F in proper position.

The operation is as follows: In Figs. 1 and 2 the brakes and parts whichoperate the same 5 are shown in their normal position, out 0faction, andthe train is supposed to be moving in the direction of thc arroW,Fig. 3.If, now,

from any cause,the adjoining ends oftwo cars come together,theprojecting end r of the rod 'Io Ewill come in contact with the inside ofthe head of the draw-bar, which will push the rod E backward, and thehook fon the casefwill engage with the bar e, which will cause the yokeD to be brought into the position shown in Fig. 8,the roller dcominginto contact with the axle B', and in consequence thereof the roller dwill be rotated, winding the rope m thereon and setting the brakes G GCnarily the axle B will rotate in the divided zo sleeve; but as the rope'm passes around such sleeve when the tension on the rope becomessufficient the sleeve will be clamped upon the axle B andwill rot-atewith it, and this will aid in setting the brakes. When the roller d isincontact with the axleB, as shown in Fig. 3, the yoke will be swung sothat the bar e' will be carried away from the hook f3 of the casef onthe bar F, so that the longitudinal movement of this bar will not actupon the 3o yoke. When the train moves in the opposite direction, thebar F will act upon the yoke "when two adjoining cars come together,bringing the roller d into contact with thc axle B' and setting thebrakes, substantially as before described, at which time the bar e willbe carried away from engagement with the hook f', so that it cannot actupon the yoke. The springs g g in the cases ff, respectively, serve thepurpose of relieving` the yoke from 4o too great strain when by a suddenmovement of the operating-rods E or F the roller-upon one end of theyoke, or some other part, is brought into contact with the axle. Thespring h serves the purpose of returning the rod E to its normalposition (shown in Fig. 2) when the rod E is` released by the separationof the cars. When from any cause, either from the slackening of thespeed ofthe locomotive or as the result of going down a grade, the endsof two 5t adjoining cars come together, thus moving the rod E, throughwhich the yoke is operated, the brakes will be brought into actionautomatically, and whenever, from an increase 'of speed or other cause,the cars separate the brakes will be released. When backing a train, thebrakes would be operated if no device were used to prevent their action.The ofiice of the short ropes o p is to prevent the action of the brakeswhen backing. These 6o ropes are arranged to be wound upon the rollers dd in a vdirection opposite to that in which the ropes which operate thebrakes are wound on such rollers, so that in backing the rope whichoperates the brakes will be unwound from the roller and the proper shortrope will be wound thereon, so that although Ordi- A in backing one ofthe rollers will Vbe brought in contact with the axle, yet the windingof the short rope on the roller will have a tendency to draw the yokeand roller away from the axle, so that the friction between the rollerand axle will not be sufficient to operate the brakes. These short ropeso p may be attached at one end to some part of the car-frame instead ofto the rods EF. The rope which op crates the brakes maybe connected tothe levers used for that purpose instead of being connected to thebrakebars, as shown.

'Ihe divided sleeve maybe of such length that before too much pressureis applied to the brakes the sleeve will rotate upon the axle.

I have only shown brakes at one end of the car. They may be used,however, at both ends, if desired, and may be located in any usualposition,the operatingropes being properly arranged and connected.

I have shown only Aone car; but the several cars of the train aresupposed to be provided with the devices described for operating thebrakes.

I have described m, o, and p as ropes. Of course wire cables or chainsmay be used. Of course the projecting ends of the rods E F might bearranged to be acted upon by an adjoining car; butsuch projecting endswill be much better protected when arranged to ,be acted upon by thehead of the draw-bar, as described.`

WhatI claim as new, and desire to secure by Letters Patent, is asfollows:

l. In combination with a car, a pivoted yoke, D, carrying rollersdd',and sliding rodsE F. adapted to operate the yoke and bring one of therollers in contact with an axle, substantially as and for the purposespecified.

2. In combination with a car, a pivoted yoke, D, carrying at its endsrollers d d', sliding rods E F, adapted to operate the yoke, brakes GG', and a rope or chain, m, to operate the brakes, substantially asspecified. 3. In combination with a car, a pivoted yoke, rollers d d',sliding rods E F, brakes, a divided sleeve, j 7c, on one of the axles,and a rope or chain, m, substantially as specified.

4. In combination with a car, a pivoted yoke, rollers d d', rods E F,brakes, a rope or chain, m, and ropes or chains o 19, substantially asand for the purposes specified.

5. In combination with a car, a pivoted yoke, D, carrying rollers cl d',sliding rods E F, eich having at its inner end a case, f and f,on whichis a hook, f and f3, to engage with one of the bars or rods e e',springs in such cases, a return-spring for each of the sliding rods, anddraw-bars, all constructed and arranged substantially as shown anddescribed, and for the purposes specified.
